In Chinese mythology, dragons and clouds go together: dragons create clouds with their breath, bring life giving rain, and are often pictured surrounded by stylized clouds. (Photo above from nationsonline.org.)
So when I was working on the lace dragon for the Dragon Lace Pullover, I also experimented with some lace clouds. I wanted them to be swirling and asymmetrical, and I tried out a couple of different sizes. I liked the results, but didn't end up using them for the Dragon Lace pullover because I thought the overall design would end up being too busy.
Recently my cloud swatches turned up, but when I went looking for the charts I had drawn with them, I couldn't find them. So I guess if I want to use them for something, I'll have to recreate the charts from the swatches (a PITA, for sure!). Oh well :-/
